There's some nice main-handers out there, but at this day of age all 1h are "one-handers" there's no main handers anymore these days. Problem is you can't transmog "mainhand" unless the sword you're wearing is a main-hand too so if its a "one-hand" it can't be transmogged since it's not the same "type" bespite them both being 1-handed swords. This is kinda silly and all weapon types should work the same. One handed sword == One handed sword no matter if its main or one-hand.

Yup, we're hoping to allow you to transmogrify items that share animations, like polearms and staves, so main hand/one hand won't be an issue any more once this goes live. Still aiming for 5.2 as far as I know :)
